The Texas Instruments TPS542941RSAR is a versatile dual channel synchronous step-down switching regulator designed for power management applications. It operates with an input voltage range of 4.5V to 18V and provides adjustable output voltages from 0.76V to 7V.
This device features integrated FETs with low on-resistance (150 mΩ high side, 100 mΩ low side) and supports output currents of 2A for channel 1 and 3A for channel 2. The D-CAP2 control mode ensures fast transient response and eliminates the need for external loop compensation components, making it compatible with ceramic output capacitors. It operates at a switching frequency of 700kHz.
Key features include soft start (1ms), power good indication, and comprehensive protection mechanisms such as cycle-by-cycle over-current limit, OCL/UVLO/TSD, and a hiccup timer for overload protection. The Auto-Skip Eco-mode enhances efficiency at light loads. The TPS542941RSAR is available in a 16-QFN (4x4 mm) package and operates within a temperature range of -40°C to 85°C.
This component is suitable for various power supply designs requiring efficient and stable voltage regulation. Its integrated nature and robust feature set simplify board design and reduce component count.
